DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 As shown, a clamping assembly of a CNC machine tool includes a clamping disk group 1, and the clamping disk group 1 includes a bottom ring frame 11 and a top ring frame 12. The top ring frame 12 is coaxially arranged on the upper end surface of the bottom ring frame 11, and the top ring frame 12 is fixedly connected to the bottom ring frame 11. A mounting groove 120 is opened on the top ring frame 12. A movable seat 2 is slidably installed between the bottom ring frame 11 and the top ring frame 12. A locking bolt 3 fixed to the top ring frame 12 is installed on the movable seat 2. A side clamp 4 is arranged on the inner side surface of the movable seat 2, and an electric cylinder 5 for driving the side clamp 4 to move is arranged in the movable seat 2. By setting the structure of the clamping disk group 1, it is ensured that the top ring frame 12 is set on the bottom ring frame 11, so that the movable seat 2 can be installed through the bottom ring frame 11 and the top ring frame 12, ensuring that the number of movable seats 2 can be rotated when needed, and the setting of the mounting groove 120 ensures that the movable seat 2 can be stably installed between the bottom ring frame 11 and the top ring frame 12. After being installed between the bottom ring frame 11 and the top ring frame 12, it can also be slid to adjust the clamping position, and then the locking bolt 3 is used to limit and fix it, ensuring that the movable seat 2 can be stably installed on the clamping disk group 1. At the same time, by setting the side clamp 4 and the electric cylinder 5, it is ensured that the electric cylinder 5 drives the side clamp 4 to clamp the product, which is easy to stably clamp and fix the product.

[0025] Reference Figure 3 and Figure 4As shown, a connecting block 13 is arranged between the top ring frame 12 and the bottom ring frame 11, and the connecting block 13 is fixedly connected to both the top ring frame 12 and the bottom ring frame 11. The setting of the connecting block 13 ensures that there is a certain installation space between the top ring frame 12 and the bottom ring frame 11, which is convenient for the installation and sliding adjustment of the movable seat 2. A connecting plate 121 is arranged on the outer surface of the top ring frame 12, and the connecting plate 121 is integrally formed with the top ring frame 12. The setting of the connecting plate 121 ensures that the clamping disk group 1 is better fixedly installed and used. Positioning holes 122 that cooperate with the locking bolts 3 are evenly opened on the outer surface of the top ring frame 12. The setting of the positioning holes 122 ensures that the movable seat 2 can be positioned after the locking bolts 3 are inserted into the corresponding positioning holes 122, so as to avoid the movable seat 2 from moving during the clamping process.

[0026] Reference Figure 5 and Figure 6 As shown, the movable seat 2 includes a connecting shell 21, an inner plate 22 and an outer arc plate 23, the inner plate 22 and the outer arc plate 23 are respectively arranged at the two ends of the connecting shell 21, and the inner plate 22 and the outer arc plate 23 are integrally formed with the connecting shell 21. The structural setting of the movable seat 2 ensures that the inner plate 22 and the outer arc plate 23 are connected to each other through the connecting shell 21, so that when in use, the inner plate 22 and the outer arc plate 23 are clamped on the inner and outer sides of the top ring frame 12, ensuring that the movable seat 2 can be stably slidably installed on the top ring frame 12. The lower end of the connecting shell 21 is provided with a receiving groove 211 for installing the electric cylinder 5, and a fixing plate 212 is arranged in the receiving groove 211, and the fixing plate 212 is fixedly connected to the connecting shell 21. By providing the receiving groove 211 at the lower end of the connecting shell 21, it is convenient for the electric cylinder 5 to be stably installed, ensuring that the electric cylinder 5 can push the side clamp plate 4 to be flexibly clamped when in use. A plurality of anti-skid grooves 41 are evenly formed on the side clamping plate 4 , and the anti-skid grooves 41 are arranged to ensure that the side clamping plate 4 is clamped more stably.

[0027] Working principle: When actually clamping, first install the clamping disc group on the equipment through the connecting plate, then select the corresponding number of movable seats according to the shape of the product to be clamped, and install the selected movable seats between the bottom ring frame and the top ring frame. Then you can adjust the position of the movable seat. After adjusting the corresponding position, you can turn the locking bolt to the corresponding positioning hole to fix it. Finally, after placing the product in the clamping disc group, you can start all the electric cylinders, and use the electric cylinders to drive the side clamps to clamp and fix the product at different positions.
